Have you ever heard that ringing sound coming from an old TV? Well, that never happens 
anymore because TVs today use LEDs or other advanced technology. That old high-pitched 
whine came from the transformer that drove the cathode ray tube. 

Even today when I hear that sound it sends a shiver down my spine, but I want to recreate 
that sound in this circuit.

Annoying TV Sound Circuit 

Step 1 — Annoying TV Sound Circuit 

• Follow this schematic and put the 
components on the breadboard, or 
if you want you can solder it on 
some perfboard. 

Step 2 

• In the end it should look like this. 
There are not many parts so it's 
easy to build. 

This circuit is great for annoying someone, and because of the high frequency sound it bounces 
off walls making it hard to find.
